Hey guys this is actually my first post ever on Bimmerfest, and i have some questions for everyone, if you could please help. I just bought the ac roof and trunk spoiler for my car, and they look great and are just what i wanted. what i am worried about is the installation. i read through your post and it gave me rough ideas about the glue and everything, but can anyone elaborate. I wouldent mind doing it myself to save the cash but if need be i also dont mind spending the cash to ensure that its done right. I dont want it coming off later down the road. Is the m3 tape really enough or should i use the glue as well?

You need to remove the wax from the area where the spoiler goes. then spread the "glue" which is actually an accelerant for the glue on the 3M tape. Press down on the spoiler and yer done. I used blue painters tape to mark up how the spoiler sits.

i did mine twice as the tips start to come loose. The bumper is firmly glued, just the tips separating slightly due to high summer heat. i don't think screws are a good idea as I would worry about water getting into the trunk.

I love and hate the idea of the screws, i know it would stay in, but idk if i could get myself to doing that to my car haha. *oceans10* i believe you said you got your spoiler from BMWchop to. I got two cleaning cloths, two tubes of primer application, and another tube which i assume is the glue, and two q-tips, did you get this as well? Are the two tubes of primer application the stuff that takes off the wax? sorry for my ignorance but these are some of my first mods. I appreciate the help and the amazingly quick replys.
would i need to sand my trunk at all or the spoiler to make the glue stick? the spoiler looks as if its already sanded or grooved. As well as, would i need to put the glue over the m3 tape?
Your steps on page one helped, but i dont know exactly how to go about things step by step with all the glues and stuff they gave me.

I bought my painted M5 lip spoiler from Painted King on eBay for $99 shipped via FedEx. It arrived in a little over a week. They custom painted it Platinum Gray Metallic (a color not listed by Painted King or Chop Shop) and it looks flawless, in fact, the paint job on the spoiler is better than on the car itself.

I wiped off the wax with a little alcohol pad that came with the kit. Then applied the glue accelerant and pressed the spoiler onto it 9after removing the orange strips). Having marked up the edges with blue tape it was easy to fit it. It sticks very well, not gonna come off. My only issue is the tips lifting slightly, but it's not that noticable. Screws would certainly cure that, but they would have to be quite long and then I worry about leaks.

I don't think I could bring myself to drill. Yes, if the hole were properly primed after drilling and the hole was large enough to not contact the screw passing through it and a rubberized grommet were used then probably rust and water entry could be prevented.

But I will always hold the memory of my father's first BMW, a brand new 1980 528e (E12 series). In those days dealer installed rust-proofing was popular (Ziebart). The idiot dealer drilled holes all over, sprayed the inner body with tar and then slapped plastic plugs into the holes. Even in those days BMW provided painting and undercoating from the factory far superior to American cars. The car was still in the family 10 years later, and the only place the car ever rusted was at each and every one of those holes they drilled in the car.

For both the Roof spoiler and the lip spoiler, I made sure i put additional lines of double-sided tape near the edges of each spoiler. If you look at the underside of the roof spoiler, you'll notice that it's recessed in the middle moreso than the edges. Putting tape in the middle won't allow the full strength of the tape to be used because the edges of the spoiler will touch the glass moreso than the middle. Put some additional tape along the edges and your roof spoiler won't go anywhere, guaranteed. I can probably lift my car by its roof spoiler...it's on there that tight.
Definitely use the adhesive promoter for the trunk spoiler. It works awesome!

ok cool. well has anyone had any problems with the glue when you take the spoiler off? something like it taking of the paint or anything, ive read a couple other comments on different posts about this problem, everyone asks abotu it but no one has actually had the experience to talk about it

I've been wanting to put an ACS type trunk spoiler on for a couple years, but never knew what ebay seller to trust or if it would be any good.
After reading this thread, I just bought it off of BMWChop.
Thanks for the info and I'll post pictures once it's on.

Ordered it from BMWChop (in Taiwan) on a Friday, and it arrived on the following Tuesday ... hooray for Federal Express! The box and spoiler were in perfect condition. The price has gone up a bit, from $92.00 to $98.00 including shipping ... but with competing products costing 2 to 3 times more, it's still a great price.

I installed it like Oceans suggested (marking with blue tape). The double-sided mounting tape came separate ... a roll of 5mm 3m core 4-1000, so I applied the tape to the spoiler a couple of days in advance and let it sit. Then I washed trunk area with Dawn dishwashing soap to remove the wax, and after drying it wiped the area with alcohol swabs. After fitting and marking the mounting location, I applied the primer and waited about an hour before installing. As the instructions suggested, I removed a few inches of the tape covering, and then fitted the spoiler, pulling back the tape covering a few inches at a time. (It worked just as the instructions said ... even though the spoiler was contacting the trunk.)

Spent some time pressing the spoiler down (especially the tips and front portion), and then removed the blue tape. Because I was a bit too liberal when applying the primer, there were a few areas that needed to be cleaned up ... WD40 to the rescue! (with Q-Tips). Waxed it today, and as Oceans said it looks OEM. As far as I can tell, the paint (Jet-Black) matches perfectly.

Really happy with the look, and just hope I installed it properly ... but right now it feels really solid. Taking a 2500 - 3000 mile (round trip) to Massachusetts in the near future, so that should be the test.

I had one installed from bmwchop in January and it started peeling up one the second day. Ultimately, it came up so badly I took it to my BMW body shop and replaced it with one directly from Germany. The two lips look identical and the paint job was perfect from BMWChop, but the Taiwanese version didn't work out for me. Maybe luck of the draw...
